You can run the program without
MBONE connectivity. But, you can only send multicast packets inside
your local subnet.

II. Instructions

A. Setup

First create a subdirectory.
Place the logger.zip file in that subdirectory. Unzip the logger.zip
file. This will create two subdirectories -- ver1 and ver2 along
with the documentation files.

B. Starting the Application

To start the application
go to the following subdirectory

..\ver2\audio\

Enter "java AudioPlayer"

You will get the following user
interface.

C. Recording Audio

First choose the "File"
menu. Then choose "New". This will give will give you an empty
linked list to store the audio packets.

Next, in the filename field
type the name of the file (ie audio.vat). Next, type in the IP address,
the port number. At this stage, don't worry about the TTL field.
Next, type in the number minutes you want to record. If you want
to record until you press the stop button, type in "0". Lastly, press
the "RECORD" button.

To stop the recording press
the "STOP" button.

To save the file. You
need to choose the "File" menu and choose "Save".

To save the file with another
file name. Choose the "File" menu and choose the "SaveAs" button.
This will allow you to choose the subdirectory and type in the new file
name.

NOTES:

This version uses a linked list to store the packets before saving them
to a file. I have only tested the application for a few minutes at
a time. If you start recording hours of audio, the application will
no doubt use more memory.

D. Playing Audio

To play audio.
Start your "vat" application. Note the IP address and port number
you have chosen.

Choose the "File" menu.
Then, choose "Open". You will get a chance to pick the file you want
to play.

Next fill in the following
fields: IP address, port number and TTL. The IP address and
the port number should be the same as the one you used for the "vat" application.
The time to live (TTL) field determines the number of hops the packet will
travel. Use TTL of "1" to keep the audio packets inside your subnet.

Press the "PLAY" button to
start the audio. Press the "STOP" button to stop the audio.

E. Fast Forward

If the file has already been
opened, press the "FAST FWD" button. If the file has not yet been
opened, choose the "File" menu and choose "Open". Then select the
file you want.

To stop the fast forward,
press the "STOP" button.

F. Rewind

If the file has already been
opened, press the "REWIND" button. If the file has not yet been opened,
choose the "File" menu and choose "Open". Then select the file you
want.
